Market-leading online detection limits for VOCs reaching ppqv-level with ULTRA-PURE ion source.
The best available detection limits for online trace gas analysis now also with H3O+, NO+ and O2+ as precursor ions.

Quadrupole or time-of-flight mass spectrometer
Since 1998 IONICON produces and develops PTR-MS instruments. Nowadays nearly all our analytical instruments are based on a TOF-MS. Learn why and decide what type of detector is the best for your analytical objective.
Here are some tips which might help you to decide what type of detector is the best for your analytical objective:

"Our group uses Ionicon PTR-MS and PTR-QiTOF instruments to study the sources, chemistry, and impacts of atmospheric organic compounds across a diverse range of environments. We use these instruments because the combination of sensitivity, mass resolution, and fast time response provides an important toolset for our research."

"At Wageningen UR we see many research applications for the IONICON PTR-QiTOF. It’s easy use, sensitivity, accuracy and on line detection without the need of prior treatments makes it a high potential instrument for all kinds of diagnostic and quality oriented research, going from environmental issues, to food and to health biomarkers."

"We use IONICON PTR-MS and PTR-TOFMS instruments for real-time measurements of a broad array of VOCs in the atmosphere, including ecosystem and aircraft scale flux measurements, direct emissions from plants and microbial cultures, controlled laboratory oxidation studies of VOC reactions and secondary aerosol formation, and field studies of atmospheric chemistry and air pollution. The rapid response and low detection limits made possible by these instruments are critical to our scientific investigations."

Direct Sampling and Analysis of Atmospheric Particulate Organic Matter An international team of researchers from the University of Innsbruck (Austria), the IRCELYON in Lyon (France) and the University of Oslo (Norway) recently studied the application of the new CHARON Particle Inlet to directly sample and analyze the chemical composition of atmospheric sub-µm particulate organic matter […]

Analysis of Complex Flavors in Real-Time with Ultra-Low Detection Limits For many years PTR-MS instruments are considered a gold-standard in many applications when it gets to the quantitative online analysis of very low concentrated VOCs without sample preparation. Among the early adopters of this unique technology that was commercialized by our company back in 1998, […]

Indoor Air Quality

Room-air VOC detection and monitoring

Real-Time measurements of VOCs causing smells or adverse health effects.
Monitoring of chemical contamination related to the Sick Building Syndrome. Sensory impact on passengers in aircraft cabins, cars (VIAQ) and workers in offices or family homes.

Petrochemical Applications

Automotive

Real-time vehicle exhaust analysis

Monitoring exhaust gas from combustion engines, emitting a large number of different compounds and with rapidly changing concentrations due to variations in operating conditions, necessitates an instrument that measures in real-time and with high sensitivity – an IONICON PTR-TOFMS.

Biotechnology

On-line Monitoring of Bioprocesses

IONICON PTR-MS systems can analyze trace gas concentrations of volatile metabolites in the off-gas of bio-pharmaceutical fermentations in real-time. This highly relevant process related information can be used for on-line process monitoring and process control.
